MINING MACHINE GATHERING HEAD Russian patent published in 2018 - IPC E21C27/24 E21C35/20 E21D9/12 

FIELD: drilling of soil or rocks; mining.

SUBSTANCE: group of inventions refers to mining machines with a gathering head. Gathering head is installed at the front end of the mining machine. Gathering head has a front end and a rear end, the rear end being intended to be positioned adjacent to the mining machine. Head comprises at least one base extending along the length of the head, the base having a surface of the base for contacting the material collected by the head, a pair of side walls, disposed at the longitudinal ends of the base, at least one back plate, a shelf extending along the length of the head and descending, projecting forward and backward from the base, providing a leading edge of the head. Each of the side walls has a side surface for contact with the material and tapering inwardly in the widthwise direction of the head from the front end to the rear end. Each lateral surface narrows outwardly relative to the surface of the base from the lowest region to the uppermost region of each side surface, directing the flow of material to the surface of the base and the material contacting surface. In this case, the back plate has a material contacting surface, extending upward from the rear region of the surface of the base and continuing in the lengthwise direction of the scraping head between the side walls.

EFFECT: technical result is the elimination of the need for additional raking feet, facilitating the movement of the extracted material.
